Feeders for Threshing-Machines; and I do de clare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to self-feeders for threshing-machines, and it isdesigned more particularly as an improvement on the selffeeder disclosedin Letters Patent No. 530,246, of December 4, 1894, granted toSeverance, Jamison, and Braucht.

The novelty and advantages of my present invention will be fullyunderstood from the following description and claim when taken inconjunction with the annexed drawings, in which- Figure 1 is a plan viewof my improved selffeeder complete, the same being shown in its properrelation to the receiving end of a threshing-machine. Fig. 2 is asection taken in the plane indicated by the line 00 w of Fig. 1. Fig. 3is a section taken in the plane indicated by the line .2 z of Fig. 1.Fig.4 is an enlarged detail section taken in the plane indicated by theline y 3 of Fig. 1. Fig. 5 is a section taken in the plane indicated bythe line to w of Fig. 4 Fig. 6 is a detail enlarged perspective view ofa portion of the apron. Fig. 7 is a detail perspective view of one endof the lateral feed-trough, and Fig. 8 is a detail view illustrating thefriction-clutch.

In the said drawings similar letters designate corresponding parts inall of the several Views, referring to which- A. indicates thecylinder-casing, B a part of a cylinder, and U the concave, of anordinary threshing-machine, such parts being here shown simply for thepurpose of illustrating my improvements in connection therewith Dindicates a horizontal frame. This frame sprocket-wheel d and aband-pulley d, the latter being'designed to be connected by a belt (notshown) with any suitable-driving part of the threshing-machine.

Gr indicates forks. These forks carry at a suitable point in theirlength boxesf, in which the cranks of the shaft'F are journaled, so thatsaid forks will be given a vertically-rotatable motion during the rotarymotion of the crank-shaft. I

Rising from opposite sides of the frame D are uprights H, which aresecured to said frame and are connected at their upper ends by across-bar I. On this cross-bar are arranged 1ug-journals g, and in theselugs are pivoted one end of arms J, the opposite ends ofwhich arepivotally connected to the upper ends of the forks, as shownat h. Theframe Dis provided with side-boards K, which may be of suitable height.The angular irons or braces E are extended at their rear ends beyondtheframe D, as shown, and are formed with bearings n for a purposepresently described.

M indicates an apron-frame which has the forward ends of its side bars prabbeted, as indicated by (1, (see Fig. 3,) to interlock with thecorresponding]y-rabbeted rear ends of the boards K of the frame D, so asto hold the apron-frame, which bears at its forward end on the frame D,in a horizontal position, as illustrated. The said apron-frame isprovided at the forward ends of its side bars 19 with lug-eyes r, whichare designed to register with the eyes 91 of the irons E on the frame D-and be pivotally connected therewith by pintles s, as shown. This modeof connection permits of the apron-frame being swung up against the rearof the frame D, the rear ends of the side boards K of said frame beingcut away, as shown, so as to permit of the apron-frame M when not in usebeing swung forward of the perpendicular, so as to enable it to restagainst the frame D without tendency of falling.

The apron-frame M comprises the side bars IOO in the side bars 19 andhas one end extended and provided with a sprocket-wheel 00 for a purposepresently described. The rear roller 4), however, is journaled in blocksy, and these blocks, which are arranged in slots .2 in the bars 17, havethreaded apertures to receive screws (0, (see Fig. 7,) which arejournaled in the end bar 6 of the apron-frame and are designed totighten the feed-apron whenever necessary.

The apron-frame M is provided in each of its side bars p with the twosockets b to receive studs 0 of the removable side guard d, and it isalso provided in said side bars 1), adjacent to the rear ends thereof,with sockets c to receive the depending studs f of the removable endguard g. The side and end guards d g are made removable, so that whenthe apron is not in operation they may be removed to permit of theapron-frame M being swung snugly against the rear end of the frame D.The side guard d is also made removable, so that it may be placed oneither side of the apron-frame when the lateral feedtrough (presentlydescribed) is arranged at the opposite side thereof.

The apron-frame M is provided in each of its side bars 1) with sockets hto receive the hooks 11 at the inner end of the lateral feedtrough N,and it is also provided on each of its side bars with hooks 7" for theengagement of the connecting-chain 7; at the inner end of thefeed-trough.

The feed-trough N has the side boards 0, the rotatable shaft N,journaled in suitable bearings, and the cylinder P, journaledtransversely in the opposite end to receive the endless feed-belt Q.

U indicates two uprights which are connected to and rise from the sideboards of the feed-trough N, and XV indicates two uprights arranged oneon each side of the trough N and in advance of the uprights U. Fixed onthe uprights \V are rack-bars p, with which engage pinions q, fixed on atransverse shaft r, journaled in the feed-trough and extending acrossthe same. This shaft 1' has a crank s at one end, through the medium ofwhich it may be rotated, and when it is rotated in one direction it willbe seen that the uprights V will be raised, while when it is rotated inthe opposite direction said uprights will be lowered. In order to lockthe uprights XV in their adjusted positions, the pawl t is provided,which is normally held in engagement with one of the pinions g by aswinging piece a, as better shown in Fig. 4:.

Journaled in the upper ends of the uprights \V is a transverse rod w,and on this rod are loosely arranged sleeves Z, which have integraldepending branches a J ournaled in the fixed uprights U is a crankshaftb and 011 one end of this crankshaft is a band wheel or pulley 0 whichis designed to be connected by means of a band (1 with a band wheel orpulley e on one end of the shaft 1, so as to receive motion from thelatter shaft and impart the same to the crank-shaft W.

A indicates reciprocatory bars. These bars may carry cutters B to cutthe bands on the bound bundles of grain, and when loose grain is usedthe cutters may be removed and spreader-fingers may be substituted. Thebars are journaled at their forward ends in the arms a of the sleeves Zon the rod 20', which is of a less altitude than the crankshaft b", andthe upper or opposite ends of said bars are journalcd in the cranks h ofthe shaft 71 Bythis construction it will be seen that as motion iscommunicated to the shaft 0 the bars A will be given a verticalreciprocatory movem ent,and as the cranks of the shaft 1) are disposed.in opposite directions some of the bars will be moving forwardly whileothers are moving rearwardly, thereby more effectually cutting the bandsor spreading the grain, as the case may be.

G indicates a short shaft which is journaled in a bracketD', connectedto the side of the feed-trough N.

E indicates a s procket-wheel which is loose 011 the shaft 0, but isheld against lateral movement thereon by suitable means, and F indicatesa beveled gear-wheel which is fixed on the shaft 0. The beveledgear-wheel F meshes with a corresponding wheel II on the shaft P totransmit motion to the belt of the feed-trough, as shown.

The sprocket-wheel E on shaft C is rotated from the pulley (Z of shaft Fthrough the medium of the sprocket-belt G, and said wheel. E is normallyfixed on the shaft 0, so as to transmit motion thereto through themedium of a suitable frietionclutch B a type of which is illustrated inFig. 8. As shown, the sprocket'belt G takes over and engages thesprocket-wheel or on the shaft w, as shown, whereby it will be seen thatit will drive the feed-apron o in a forward direction. The friction-c111tch B com prises a conical receiver a fixed to the sprocket-wheel E, anadj ustable cone 11 which is splined on the shaft (1" and has aperipheral groove 0 and a coiled spring d", which is interposed betweenan enlargement e on the shaft and the cone Z2 and is designed tonormally press the said cone into and against the conical receiver 0. soas to can se the shaft 0 to turn with the sprocketwheel. The cone b isdesigned to be adjusted by a lever f which is fulcrumed at anintermediate point of its length and has one of its ends seated in thegroove 0 of the cone, as illustrated.

In virtue of this construction it will be seen that when the lever f isrocked in the direction indicated by arrow the cone b will be moved outof engagement with the cone-re ceiver a and in consequence thesprocketwheel E will be rendered loose on the shaft 0, which willresultin a stoppage of the apron Q of the lateral feed-trough withoutdiscontinuing the rotation of the shaft w and the operation of the barsA. Thus when a very large quantity of grain is deposited on the apron vof the apron-frame M the belt Q of the feed-trough may be stopped untilthe said apron c has properly conveyed the grain to the forks G. Whilethe belt Q will be stopped, as stated, the movements of the bars A willnot be discontinued, and in consequence the knives B will cut the bandsof the bundles of grain on the idle apron-belt Q, or if fingers areemployed in lieu of said knives they will serve to thoroughly open andseparate the grain on the apron, so that when said apron or belt isagain started no choking will ensue. It will be obvious from theforegoing that by adjusting the uprights W and rod m the amount of grainpassing under the knives B may be regulated.

In the practical operation of the invention the grain is thrown into thefeed-trough and carried by the endless belt thereof beneath the cuttersand then discharged in a loose state upon the apron 'v. This will carryit to the frame D, and as it enters the same it will be taken by thereciprocatoryforks- G and fed into the cylinder-casing of thethreshing-machine.

WVhen the feed-trough N is to be arranged at either side of theapron-frame M, it is obvious that the gearing at one side of thethreshing-machine, aproneframe M, and feed-trough N must be duplicatedat the opposite sides thereof. It is not deemed necessary, however, toillustrate such gearing.

The employment of the lateral feed-trough N is advantageous because itextends or reaches out farther from the threshing-machine than theordinary end feed and permits of a large amount of grain being fed tothe machine without the necessity of moving the same. Said lateralfeed-trough also permits of the employment of a low derrick instead ofthe high derrick which must be of necessity employed in conjunction withthe ordinary end feed-trough, and it also enables the attendants toquickly get the machine in operation when it arrives at a setting,inasmuch as the derrick sets on one side of the machine and out of theway.

Having thus described my invention, what I claim is A grain-feeder forthreshing-machines, comprising a frame D, a crank-shaft journalcd insaid frame and adapted to operate grainfeeding forks, a sprocket-wheelcl, fixed on said shaft, an apron frame pivotally connected to andarranged in alinement with the frame D, and havinga removable side guardand a removable end guard, shafts journaled in said frame, an endlessapron taking around said shafts, a sprocket-wheel 0c, fixed on theforward shaft, a lateral feed-trough detachably connected to one side ofthe apron-frame, shafts journaled in said feed-trough, a feedbelt takingaround said shafts, aband-wheel e fixed on the forward shaft, a beveledgearwheel H, also fixed on the forward shaft, a short shaft journaled ina bracket connected to the feed-trough and having a gear F, engaging thegear H, and also having a loose sprocket-wheel E, a friction-clutch fordetachably fixing the-wheel E, on the shaft, a sprocket-belt takingaround the sprocketwheels E, d, and passing over and engaging thesprocket-wheel 0a, a transverse shaft j ournaled on the feed-trough andhaving cranks at intervals in its length, bars connected with andadapted to be actuated by the said cranks and also adapted to carryknives or grainspreading fingers, a band-wheel c fixed on thecrank-shaft, and a band taking around said wheel 0 and the band-wheel 6all substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
